ICD-10 Code G44.319 – Acute post-traumatic headache, not intractable (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G44.319 – Acute post-traumatic headache, not intractable
What it is
This code identifies a headache that begins soon after a head injury or trauma and is not described as intractable. Use it when the record supports an acute post-traumatic headache rather than a chronic or persistent headache pattern.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the headache is temporally linked to recent trauma and may be described as new onset after injury, with or without associated concussion symptoms.
When to use this code
Use G44.319 when the provider documents an acute headache caused by recent trauma and explicitly states it is not intractable. This is appropriate when the note links the headache to the injury event and does not describe a chronic post-traumatic headache. If the timing or cause is unclear, check documentation.
Do not use for
Do not use this code for intractable post-traumatic headache or for headaches unrelated to trauma. If the record supports a different headache type or the provider does not document post-traumatic origin, check documentation.
Coding tip
Confirm both the acute post-traumatic relationship and the nonintractable status in the provider note before assigning G44.319.
